I am trying to come up with some way that I can cause an alarm to go off when one of my armed motion sensors is tripped. Anything that will produce a loud noise and that I can plug into an appliance module should work. Perhaps a bell or a siren. I have also given some thought to something that could play a loud recording .
Would this help:

There were few Z-Wave sirens discussed and cj explained how to connect a regular one to an appliance module…
